C Language Example - Numeric Comparison
C Language ExamplesCompare two numbers
In the following example, two integer variables are defined and compared using an if statement. You can first look at the logic diagram:
Example
#include <stdio.h>
int main() {
int a, b;
a = 11;
b = 99;
// Alternatively, use the following code to let the user input two numbers in the terminal
// printf("Enter first value:");
// scanf("%d", &a);
// printf("Enter second value:");
// scanf("%d", &b);
if(a > b)
printf("a is greater than b");
else
printf("a is less than or equal to b");
return 0;
}
Output result:
a 小于等于 b
Compare three numbers
In the following example, two integer variables are defined and compared with three values using an if statement. You can first look at the logic diagram:
Example
#include <stdio.h>
int main() {
int a, b, c;
a = 11;
b = 22;
c = 33;
if ( a > b && a > c )
printf("%d is the largest", a);
else if ( b > a && b > c )
printf("%d is the largest", b);
else if ( c > a && c > b )
printf("%d is the largest", c);
else
printf("Two or three values are equal");
return 0;
}
Output result:
